1. Charge your battery 30% or more.
    
2. Turn off the phone.
    
3. Press and hold the Volume Down button and the Power button at the same time until the phone turns on.
    
4. Press the Volume Down button until you see Recovery mode.
    
5. Press the Power button to restart in Recovery mode.
    
6. If you see an Android robot with a red exclamation mark, press and hold the Power button, then press and release the Volume Up button to display the menu options.
    
7. Use the Volume buttons to scroll to Wipe data/factory reset, then press the Power button to select it.
    
8. Use Volume buttons to scroll to Yes, then press the Power button to select it.
    
9. Use Volume buttons to scroll to Reboot system now, then press the Power button to select it. 
   Allow several minutes for the reboot to complete. If the phone doesn't finish rebooting, press & hold the Power button until the screen turns dark, then release it to power up normally.
    
10. If you reset your phone because you suspect a third-party app is causing problems, when you set up the phone again, be sure you don't copy all apps. Then, restore one app at a time and use the phone for a while. If the phone has no issues, install the next app and retest.

I was simply following the instructions from the phone as to how to get the phone going. I dont understand your question--'which app?" pls explain

I have just bought Moto g7 phone. I set up my password, but when I entered my password nothing happened. What should I do immediately after entering my PW. Alternatively, how can I start all over again to get my new phone to work? Thanks

I don't understand your question. In which app did you enter your password?
